SHOE

' Application med .Tune 20,

This invention relates to shoe Shanks and is disclosed in relation toa ladys welt shoe.

@ne object of this invention is to provide a staunch and stable shank structure for a shoe.

Another object of this invention is to provide a staunch and sta-ble shank structure for a shoe, said shoe adapted to be fabricated otherwise according to conventional coinm merical processes and without unusual machlnery.

Another`object of the invention is to provide a reen'lorced sole for a shoe, said sole constructed to provide a Sti' shank portion 15, lor the shoe. y i

@ther objects and certain advantages o f the invention will be more fully'set forth in the description of the accompanying drawings, forming a part of this specilication, in

which: l

Figurel is a side elevation' of a shoe with a portion of the side thereof broken away to disclose the shoe sole layers in section at the shank portion of the shoe.

Figure 2 is a sectional view taken on line 2 2, Figure 1, further detailing rthe fabrifation of the shank portion of the shoe.

Figure 3 is a bottom view of the improved sole with a portion of the sole broken away g@ to disclose a shankstidener disposed therein.

Figure 4 is a sectional view taken on line 4 4, Figure 3, detailing a sleeve arrangement embodied in the sole.` Y

Figure 5 is ectional viewitaken on line 5 5, Figure 4; howing the shank piece in section and its relation to linesfof stitching disposed at each side thereof.

. A welt shoe conventionally comprises an upper l joinedto an insole 2 to which is se. 4.0 cured an outsole 3 by means of welt 4, stitching holding the welt to the insole and the .outsole to the welt,.and a heel 5 which ishnailed at the rear end of the shoe.

According to this invention ll modify one element of this combinati0n','in this instance, the insole, by providing an insole (ofthe Gem type as disclosed) having a rear portion Vcomposed of two superpose'd layers 6 and 7. Between these two layers of the insole is placed a shank stifener 8. If desirable 1927. Serial No. 199,88.

this shank stitener can be almost as wide as the insole. The insole is stitched onA either side of the shank stidener as at 9 to secure this vshank st-iiener firmly in place upd imbed the same in the insole.

This two layer structure of the rear por tion of the insole can be provided either by adding one layer to the insole as cut, or by splitting the insole to provide two layers. The layers and stitching together provide a pocket or sleeve in the insole adapted to receive the shank stili'ening members. This manipulation of Lthe insole can be conveniently done betore "assembly of the shoe cornmences. The assembly follows any ot the 65 conventional processes,` and the invention can be practiced in relation to a. McKay, as well as .to a welt. Tf desirable, a secondary shank stitfener l0 may be used between the outsole and the insole between the inseam lips of the latter as is conventional. This shank stiltener is disclosed as held in position by tacks l1. This structure provides a shoe having a very rigid shank portion as isV particularly desirable in a shoe for a heavy person.

The construction herein disclosed is applicable to the outsole in the same manner as disclosed for the insole so that itis optional where it is used. Ttinay be embodied in both soles if desired for double shank strength.

Havingdescribed my invention, T claim:

In a shoe, a composite insole composed of a layer'of full insole dimension and outline having a marginal inseam lip extending from the underside of the fore part of said layer, a second half length layer for the shank and heel portion of the insole fixed to the underside of said first layer and having marginal lips extending from the underside of the shank portion thereof and continuous with the inseam lip of said first layer, said layers stitched together longitudinally marginally for the shank portion of the insole, and a shank stitl'ener centrally between said layers secured at its rear end to said second half length layer.

In witness whereof, I hereunto subscribe my name.
